Hi Guys,
 
Feel free to move this to hardware Mods, I just think there is more chance of one of our techies seeing it here.
 
Simply, I am trying to upgrade my RAM from 8Gigs to 16Gigs the current RAM is 1333Mhz and I am trying to put in 2x 8 gig 1600Mhz.  The motherboard manual says it is possible as long as I have a 22nm processor, which I believe I do (3rd Gen i5).  However, I have tried 2 sticks of crucial RAM which didn't work and now 2 sticks of Integra RAM and this doesn't work either.
 
The Crucial RAM wouldn't let the PC power up at all it powers on then shuts off immediately in a pulsing routine (on- off).  The Integra RAM allows it to power up but wont boot, the hard drive light just pusles on and off.  I've tried every configuration I can think of. put the old RAM back in and no problems at all.
 
Any thought's on what I am doing wrong?
 
Operating System
   Windows 8.1 Pro 64-bit
  CPU
   Intel Core i5 3450 @ 3.10GHz 30 °C
   Ivy Bridge 22nm Technology
  RAM
   8.00GB Dual-Channel DDR3 @ 665MHz (9-9-9-24)
  Motherboard
   Gigabyte Technology Co., Ltd. B75M-D3V (Intel Core i5-3450 CPU @ 3.10GHz) 24 °C
 
Any help much appreciated.
 
Many thanks.

I had the same problem when I tried to upgrade my laptop RAM from 4 to 8GB. The only difference between the two sticks that I could find is the speed. I think you will have to go for the exact spec. I see you are trying to replace 1333MHz with 1600MHz, that could be the problem. Even though it says it should work but in reality it doesn't. There are some configs that can be done in BIOS but in case of mine those settings are hidden. Try the PCWizard tool to get the exact specs of your RAM.

Thanks Satyatunes.
 
The report at the bottom comes from something similar to PCWizard, there's pages of the stuff, but, I just posted the first part.  It seems weird that the motherboard manual says it can handle it.  Most likely you are right of course.

If you go to crucial.com and use the system scanner, what does it say?

I'll take a look.

Hi,
can you have  a look,
if the same ram voltage for is required for both ram´s , 1,5 Volt or so?
1.If not, this could cause  the  problems .
2. Do the different rams have the same measure , 
for example 9-9-9-24.....
Sure you have tried different positions of the ram modules-port 1 and 3 (or 1 and 2) per sort 
and port 2 an 4 ( or 3 and 4)!
Hope it´s possible to understand ,english it´s not my first language.
 
good luck

I had this problem too, going from 16GB to 32GB. It took a few different brands before it worked, even though they were all the same specs. Fortunately I took it into the shop where I've always done my system builds/upgrades, so I didn't need to do everything through the mail!

Pragi's idea about checking the timings might be a good idea.
 
Can you lower the frequency of the RAM in BIOS to 1333Mhz? See if that allows boot up.  had a similar problem with DDR3 (1866) RAM.
If that works, you probably will need to change the timings to what is printed on the packaging or maybe a label on the RAM strip, then increase the frequency.
 

Check to find out if the DIMMs you have purchased are high density. Many motherboards will not boot on high density RAM. Low density modules are usually a bit more expensive, but work on all motherboards.
